摘要
In a reinforcement binding machine in which a wire feed device feeds externally therefrom a wire for binding reinforcements and the wire fed out by the wire feed device is bent in a loop shape by a guide part, a twisting-and-tightening mechanism comprises: a pair of hooks being capable of opening and closing, for gripping in part the wire wound around the reinforcements in the loop shape; a driver for rotating the hooks in a direction to twist the wire gripped and for selectively moving the hooks toward or apart from the reinforcements with the wire wound therearound; and a coil spring for urging the hooks such that the hooks are normally spaced apart from the reinforcements.
